Nanostructured tungsten trioxide on interdigitated microelectro- mechanical platform for ethylene gas sensor applications / Amirul Abd Rashid

In this study, tungsten trioxide (WO3) nanostructure material is integrated onto interdigitated (IDE) Micro-electro-mechanical (MEMS) platform to form a gas sensor targeting to detect ethylene gas. Traditionally, ethylene gas detection requires the sample of the gas to be collected and measured offl...
